Fantasy owners tend to overreact to whatever happened the previous week. The Fantasy Source experts are not always immune from this phenomenon, but they did a good job keeping a collective level head in this week's Experts' Picks.

There's at least one big Week 11 performer at every skill position who finds himself labeled as a "stumbler", including Bucs' breakout star Bobby Rainey.

Rainey ran for 163 yards and three TDs against Atlanta and was likely the top waiver claim in many leagues -- assuming he wasn't claimed the week before when he had a good fourth quarter against Miami. But Bill Bender sees him as a "stumbler" this week against Detroit. The reason? Matchup. Both Miami and Atlanta rank in the top nine in fantasy points per game (FPPG) allowed to RBs; Detroit ranks 20th. It's a little too early to go all-in on Rainey.

Indianapolis' Donald Brown is in the same boat after his breakout against Tennessee (tied for fifth-most FPPG allowed to RBs). This week he faces Arizona (fewest FPPG allowed), which is largely the reason Matt Lutovsky has him down as a "stumbler."

At quarterback, Craig Williams has no love for Robert Griffin III despite a 27-point day last week against Philadelphia (10th-most FPPG allowed to QBs). This week won't be as easy against the 49ers (tied for fifth fewest).

Antonio Brown's monster Week 11 came against Detroit (second-most FPPG allowed to WRs), but this time around he gets the "Joe Haden treatment" against the Browns (fifth fewest), which is enough to scare away Williams. Haden has allowed just one WR1 (Jordy Nelson) to hit double-digit fantasy points, and only one other (Torrey Smith) has even made it to six points.

Antonio Gates' TD last week against Miami (fourth-most FPPG allowed to TEs) didn't go unnoticed, but Lutovsky isn't buying Gates against the Chiefs, who have allowed just one touchdown to a TE all season and rank dead last in FPPG allowed to tight ends.
